Command Word
The TLE5012 is controlled by a Command Word. It is sent first at the start of every data transmission. The structure
of the Command Word is shown in
values. If an update command is issued and UPD is set, the immediate values are stored in the update buffer
simultaneously. This enables a snapshot of all necessary system parameters at the same time. Bits with an update
buffer are marked by an “u” in the bit type in the register description.
